Answer:
x=−4/5 or x=−3
Step-by-step explanation:
Step 1: Factor left side of equation.
(5x+4)(x+3)=0
Step 2: Set factors equal to 0.
5x+4=0 or x+3=0
x=−4/5 or x=−3
Answer:
Step-by-step explanation:
= 12 - 3
= 9
= -8 - 4
= -12
= -60 + 12
= -48
= -2 + 2
= 0
= 17
= 1
We will be using the Angle Addition Postulate in this problem.
This states that if <em>c</em> is on the interior
of <ABD, then m<ABC + m<CBD = m<ABD.
Since m<ABC is 4x + 2, m<CBD is 3x - 7, and m<AVD is 100,
our equation will be 4x + 2 + 3x - 7 = 100.
Solving from here, we first simplify the left side to get 7x - 5 = 100.
Now add 5 to both sides to get 7x = 105.
Dividing both sides by 7, we find that <em>x = 15</em>.
Now we can use the value of x to help us find m<ABC.
Since the m<ABC is 4x + 2, we can substitute a 5 in for x.
This gives us 4(15) + 2 or 60 + 2 which is 62.
So m<ABC is 62°
Answer:
The answer of your question is: x = 5
Step-by-step explanation:
It's and isosceles triangle then ∠ A = ∠C
73 = 8y - 7
8y = 73 + 7
8y = 80
y = 80 / 8
y = 10
∠ C = 8(10) -7
∠ C = 73°
The sum of the internal angles in a triangle equals 180°
∠A + ∠B + ∠C = 180°
73° + (6x + 4) + 73° = 180° Substitution
6x + 4 = 180 - 73 - 73
6x =34 - 4
6x = 30
x = 30 / 6
x = 5
